An Ohio man and his son are using the Bible to defend themselves in court against multiple charges of rape, kidnapping, and endangering children.

Via the Washington Post, the Toledo Blade reports that 53-year-old Timothy Ciboro and his son, 28-year-old Esten Ciboro, have been allowed to use the Bible as their main piece of evidence to defend themselves against accusations that they kidnapped and raped underage girls at their home in Toledo, Ohio over the span of several years.

“There’s a great deal of strategy in Scripture and I use those strategies in everything I do,” Esten Ciboro told the court last week when explaining why he and his father should be allowed to use the Bible in court as part of their defense.

Ciboro, who is acting as his own attorney in conjunction with his father, also called the Bible “the only law book that truly matters.”

Lucas County Common Pleas Judge Linda Jennings said that she would allow the two men to use the Bible during their trial, so long as they didn’t use it question witnesses.

“It’s the court’s opinion that while the Bible is very important, it is not a law book in a court of law,” she told the men.

The two Ciboros were arrested last May after Esten Cibro’s 13-year-old stepsister escaped from their basement and told police that she had been kidnapped and repeatedly raped by both men for more than a year.
